When the import was done, there should have been a minimal compat layer so that v6 tools wouldn't die when talking to a v13 system. It is too late for 8.0 to do that, depending on time and complexity I'll look in to doing that for 7.3. At this juncture there isn't a convenient stop-gap. Given that there is no central source to read for individuals updating. I think it makes sense for freebsd-update to at the very least check if it is installing on a system running ZFS v6. You'll need to talk to Colin Percival about his availability to do that. Cheers, Kip
